Single-ended and low voltage differential modes

This drive incorporates two different transceivers to allow you to use it in systems which use single-ended (SE) drivers and receivers, or in low voltage differential (LVD) capable systems which use LVD drivers and receivers.

The primary benefits of LVD technology

•Faster transfer rates.

•Reduces power consumption.

•Increases allowable cable lengths.

•Improves device connectivity.

You can configure the drive to switch between SE and LVD modes automatically or force it to operate in SE mode only. To configure this option, use the jumper illustration on page 24 (LW models) or page 34 (LC models).

Note. To operate at the Ultra2 SCSI rates in LVD mode, all devices on the same bus must be running in LVD mode. If you add any single-ended device to a bus that is operat- ing in LVD mode, all devices drop back to operating in single-ended mode. This eliminates the possibility of reaching Ultra2 SCSI transfer rates.

Caution. Do not mix LVD drives on the same bus with devices having high voltage differential (HVD) interface circuits. The circuits are not compatible and drive dam-

age may occur.

ST136403LW/LC specifications

The Seagate ST136403LW/LC is a vintage hard disk drive that belongs to Seagate's esteemed lineup of storage solutions. Known for its reliability and performance during the era of its release, this model caters to various computing needs, particularly in enterprise and industrial settings.

One of the standout features of the ST136403LW/LC is its capacity of 36.4 GB, which, although modest by modern standards, was quite impressive in the early 1990s. This size made it ideal for businesses at the time looking to store substantial amounts of data without the high costs associated with larger enterprise solutions.

The drive operates at a speed of 7200 RPM, allowing for efficient data access and transfer. The spindle speed is crucial for performance, and 7200 RPM was considered rapid for hard drives in that period. This enhanced speed translates to quicker read and write times, making it suitable for applications that require timely data retrieval.

The ST136403LW/LC utilizes the SCSI interface, a popular choice in server environments for its robustness and speed. SCSI technology facilitates the connection of multiple drives, providing the ability to network various devices and manage them effectively. The multi-device capability is particularly beneficial for enterprise applications, ensuring that data centers can efficiently manage resources.

In terms of physical characteristics, the ST136403LW/LC is a 3.5-inch form factor drive, a standard size that fits into most desktops and servers of its generation. This compatibility is vital for users looking to upgrade their existing systems without the need for significant modifications.

The drive also includes built-in error correction features, enhancing data integrity and reliability, crucial for business operations where data loss can lead to substantial repercussions. Additionally, it employs a sealed enclosure design, providing protection against dust and moisture, thereby extending the drive's lifespan in demanding environments.

Furthermore, Seagate's reputation for durability is echoed in the ST136403LW/LC, as it was designed to endure the rigors of everyday use, particularly in enterprise settings where uptime is critical.

In conclusion, the Seagate ST136403LW/LC serves as an essential piece of technology from its era, characterized by its 36.4 GB capacity, 7200 RPM speed, SCSI interface, and robust construction. While modern storage solutions have far surpassed its capabilities, this drive remains a testament to Seagate's legacy in the storage industry, reflecting the innovations of its time.
